Vehicle check-in and inspection checklist for repair, performance and off-road shops

Most arguments with customers start at the check-in, not at the invoice. A scratch nobody photographed, a warning light that was “never on before”, a job the customer swears they didn’t approve. A consistent check-in, done the same way on every vehicle, prevents most of them. This is the checklist we’d hand a new service writer.

Why a fixed checklist beats a good memory

Good service writers remember a lot. They don’t remember it the same way twice, and they’re not there every day. A checklist does three things memory can’t:

• It makes the record complete. Every vehicle gets the same fields and the same photos, so there’s no gap when you go looking for something later.
• It makes the record comparable. If the front bumper is always photo three, you can find it in ten seconds a month from now.
• It makes the conversation easier. “I take the same photos on every car” is a lot less awkward than “I’m photographing your scratches.”

1. Customer, contact and who can approve work

Before you look at the vehicle, get the people side right.

• Customer name, phone and email. Confirm them; don’t trust last year’s record.
• How they want to be contacted for questions and approvals: call, text or email.
• Who can approve work. The owner? A spouse? A fleet manager? Write the name down. If someone other than the customer will approve, note it now, not when you’re waiting on a yes.
• Pickup person, if it’s not the customer.
• Payment expectations, if relevant: a deposit on a big build, or a fleet account with its own terms.

2. The vehicle

• VIN. Scan it rather than type it. A scanned VIN decodes year, make and model and removes transposed characters.
• Plate and state.
• Year, make, model, engine, trim. Confirm what the VIN decode says against what’s in front of you, especially on swapped or modified vehicles.
• Mileage. Type it in, and photograph the odometer.
• Fuel level. In the same dash photo.
• Warning lights. Turn the key, let the dash run its check, and photograph what stays lit. Note any lights on in writing too.
• Drivability on arrival. Did it drive in? Was it towed? Does it start?

3. The concern, in the customer’s words

Write down what the customer says, the way they say it. “Clunk from the front end over bumps when it’s cold” is far more useful to a tech than “suspension noise”, and it’s the line you’ll come back to when the customer asks what they actually brought it in for.

Ask the follow-up questions while the customer is standing there:

• When does it happen? Cold or warm, at what speed, under load, turning, braking, after rain?
• How long has it been happening? Did it start after other work?
• Can it be reproduced? Would they ride along with a tech if needed?
• What do they want done? A diagnosis, a specific repair, an upgrade, a quote only?

For performance and off-road builds, add the goal: the use (daily, weekend trail, competition), the parts they’ve already bought, and anything that has to work with existing mods.

4. The walk-around photo order

Pick an order and never change it. The point is speed and consistency, not artistic photos. A sensible order:

1. Four corners. Front left, front right, rear right, rear left, each showing two sides of the vehicle.
2. Each panel. Bumper, fenders, doors, bed or quarter panels, tailgate or hatch, roof if you can see it.
3. Wheels and tires. All four, plus the spare if it’s accessible. Curb rash on wheels is one of the most common disputes.
4. Glass. Windshield chips and cracks, mirrors, lights and lenses.
5. Interior. Seats, dash, headliner, cargo area. Photograph stains and tears before a tech climbs in.
6. Dash. Odometer, fuel and warning lights (from step 2).
7. Underneath, when it matters. On lifted trucks and built rigs: skid plates, sliders, control arms, driveshafts, anything already bent, leaking or modified. A quick look under the front and rear with a light is often enough.

Photograph existing damage up close as well as in the wide shot, so the close-up can be placed on the vehicle later.

5. Existing damage and aftermarket parts

Note damage in writing as well as in photos: “dent, left rear door, approx. 2 in.” A short note makes a photo searchable and makes the signature mean something.

For performance and off-road shops, the aftermarket list matters as much as the damage:

• Lift or leveling kit, wheels and tires, bumpers, armor, lighting, winch.
• Engine and drivetrain mods, tunes, gauges.
• Anything that affects how you’ll work on it: a re-geared axle, a relocated part, a non-stock harness.

This protects you from “that part was stock when I dropped it off” and saves your tech from surprises.

6. Keys, valuables and odds and ends

• Keys. How many, fobs, a valet key, and where they’re stored in the shop.
• Lock-nut key. Locking lug nuts without the key stop a tire job dead. Ask for it, and record where it is.
• Valuables. Ask the customer to take them. Note anything left in the vehicle that they choose to leave (tools, child seats, recovery gear).
• Alarm, immobilizer or kill switch. How to start the vehicle and where the switch is.
• Wheel and radio codes, if the vehicle needs them after a battery disconnect.

7. The estimate and the authorization

The check-in records the vehicle’s condition. The estimate and the authorization record what the customer agreed to pay for. Keep them together on the same job.

• Write the estimate before work starts, even if the first step is only diagnosis. Describe the work and the price for parts and labor.
• Get the customer’s approval and record it: who approved, when, and how (signature, phone call, text or email reply).
• Give the customer a copy of anything they sign.

Some states set specific rules here. California is a well-documented example: its Bureau of Automotive Repair says an estimate is required before an automotive repair dealer (California’s term for a repair shop) performs repairs, that authorization must be obtained and recorded on the estimate before any repairs begin, and that written, oral and electronic authorizations each have to record particular details. It also requires a copy of any document the customer signs to be given to them at the time of signing (BAR, Write It Right). Rules differ from state to state. Check your state’s rules; this is not legal advice.

Additional work found during the job

Additional work is where approvals fall apart. A tech finds a torn boot, someone calls the customer, the customer says “sure”, and nobody writes it down. Then the invoice is higher than the estimate and the customer remembers the conversation differently.

Treat every addition the same way:

1. Write it up as a revised estimate or an added line: parts, labor and price.
2. Send it to the person who can approve work (from step 1).
3. Record the approval with the date, time, the person’s name and how it came in, before the work is done.
4. If they decline, record that too. A declined recommendation on file is useful the next time the vehicle comes in.

California’s guidance, for instance, says that before beginning any additional repairs beyond the original estimate, the dealer must prepare a revised work order describing the additional parts and labor and document the customer’s authorization (BAR, Write It Right).

8. The signature

The last step: the customer reviews the check-in (the concern, the noted damage and the photos), and signs. A signature on a record that lists the existing damage is worth far more than a signature on a blank work order.

Doing this in ShopJig

ShopJig’s check-in follows this flow on an iPhone or iPad: pick the customer, scan the VIN to decode the vehicle, write down the concern, work through the walk-around with photos, and get the customer’s signature on screen. Drafts are saved on the device, so a weak signal in the lot doesn’t lose a half-done inspection, and the scanning works with the camera or a Bluetooth scanner. The signed check-in stays on the job, next to the estimate the customer approves from a link. See how it fits a repair shop or an off-road shop.
